It is peak summer travel season at ONT, so passengers should anticipate longer lines. We encourage travelers to arrive at the airport AT LEAST two hours prior to their scheduled departure.

Airport management, TSA and the airlines continue to work together to develop solutions to help address passenger traffic flow from the security checkpoint on the first floor, to security screening on the second floor. The airport also implements additional precautionary security measures during these peak times for the safety and security of all our passengers.

We ask that travelers remain patient during the busy travel season and prepare in advance by arriving at the airport early, checking with their airlines for flight delays and cancellations, and following other travel guidelines offered by TSA on http://www.tsa.gov/traveler-information/summer-travel.
